If your fridge smells a little funky, but you don't have any baking soda handy, oatmeal can fill in as a natural alternative.

Oatmeal is great at absorbing oils, but it works just as well for eliminating smells. Just open up a canister of uncooked oatmeal, or pour some in a bowl, and set it in your fridge overnight. By morning, it will have neutralized the offensive odors just like a box of baking soda. Once the oats have done their job, you can even reuse them to clean a cast iron skillet.
